When dressing the antenna cables, form drip loops near the lower ends. These
ensure that water is not constantly channeled towards the connectors.
5
If the ODU is mounted outdoors, weatherproof the N type connectors fitted to the
ODU using self-amalgamating tape under a layer of PVC tape. Weatherproof the
antenna joints in the same way (unless the antenna manufacturer specifies a
different method).
To prevent water ingress, always use crimped N-type connectors at the ODU
and antenna.
6
Ground the antenna cables to the supporting structure at the correct points.
They should be grounded within 0.3 meters (1 ft) of the ODU and antennas using
the using the Cambium grounding kit (part number 01010419001).
A mast or tower may require additional grounding points, as specified in

Dress the antenna cables and attach them to the supporting structure using site
approved methods.
Ensure that no undue strain is placed on the ODU or antenna connectors.
Ensure that the cables do not flap in the wind, as flapping cables are prone to
damage and induce unwanted vibrations in the supporting structure.
